Ned, Ara,
We can use now the new StaticVarSet() function.
As we read in the 4.58 ReadMe
** Static variable - the variable has static duration (it is
allocated when the program begins and deallocated when the program
ends)
and initializes it to Null unless another value is specified. Static
variables allow to share values between various formulas.
Only NUMBER and STRING static variables are supported now (not
ARRAYS).**
We may also use Param() in a "master" code
//Master
StaticVarSet("per",Param("per",10,10,50,10));
Plot(MA(C,StaticVarGet("per")),"st",1,1);
and use it in any "slave" IB window
//Slave1
Plot(MA(C,StaticVarGet("per")),"st",1,1);
or
//Slave2
Plot(EMA(C,StaticVarGet("per")),"st",1,1);
